Mennon grey card (Standard pack) is a specialized grey card for digital photography. It is designed based on ISO standard and combined with customers’ preference of colors.

An early grey card was only used for measuring the exposure value, which might have produced a light difference during measuring the color temperature that mostly appeared to be a cold color. To revert vivid color back in scene, based on 18% grey, mennon grey card has contained traces of color element that is more suitable for digital photography. That makes mennon grey card work effectively in balancing color temperature.

Set of two flexible check cards takes guessing out of setting perfect exposure and color balance, that can only be archived with high quality Mennon Gray Cards with the uniform spectral reflectance, regardless of wavelength, color or intensity of the illumination. Each card has two sides: one side white and other is gray. The gray side used as a reference area for exposure metering while the white side enables correct white balance that is so important in digital photography. 

Using Grey Card during Photography Session (Setting White Balance)

  1. Put the grey card on the place in which the subject is and be sure that the light (natural light or artificial light) is from the same direction with the digital camera. Set your camera in manual white balance mode.
  2. Use AEL function to measure the reflected light on grey card (grey surface), as the same time the distance between the camera and grey card should be kept in about 15cm away. Re-composition and re-photograph after the value has been fixed. Then you must get the true color of present scene.
  3. To photograph a subject which seem to be far, such as the scenery, the long-range view, the beach and the snow scene, you can directly aim the digital camera at the grey card (grey surface) to measure the grey balance. But the light on grey card must come from the same direction with on the object’s.
  4. Attention, the color which is measured by grey card, is the true color of the present scene. If the color is measured under the natural light, it must be the color temperature of natural light; if the color is measured under the artificial light, then it’ll be the color temperature of artificial light. In a word, with a grey card, the scene will be reverted to its PRESENT color but the present color temperature won’t be changed. It’s also convenient to help you add light atmosphere or even mood to your works in case that you want to express colorful artificial lights and morning or evening glow.

  2. Keep an appropriate distance meanwhile photographing the grey card full-framedly with perpendicular the camera to grey card to form a 30° angle with the sunlight, grey card and camera.
  3. There should not be any shadow on the grey card. The ideal light condition to photograph grey card is under natural light, at a partly cloudy noon.
